异常信息如下：

org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.util.Date' to required type 'java.sql.Timestamp' for property 'wfsj'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [java.util.Date] to required type [java.sql.Timestamp] for property 'wfsj': no matching editors or conversion strategy found

看异常信息大概知道属性wfsj这个字段，不能完成java.util.Date 到 java.sql.Timestamp 日期时间戳的转换。后面还有提示， 没有找到匹配的conversion或editor。

conversion 在Spring中转换对象属性会用到，而editor和converter 以及formatter也是在转换对象（String –> Date, String –> Timestamp），从字符串到对象，从对象到字符串的时候会经常用到。

解决方法：

<bean id="customConfigProcessor" class="com.jp.tic.framework.flex.converter.CustomAmfConversionServiceConfigProcessor"/>

<flex:message-broker services-config-path="/WEB-INF/flex/services-config.xml">

    <flex:exception-translator ref="flexExceptionTranslator" />

    <flex:config-processor ref="configProcessor"/>

    <flex:config-processor ref="customConfigProcessor"/>

    <!--<flex:message-interceptor ref="flexMessageInterceptor" />

    <flex:message-interceptor ref="loginMessageInterceptor" />-->

</flex:message-broker>

为message-broker对象注入CustomAmfConversionServiceConfigProcessor对象，CustomAmfConversionServiceConfigProcessor是继承AbstractAmfConversionServiceConfigProcessor对象。

AbstractAmfConversionServiceConfigProcessor对象中提供了对各个类型转换serialization/deserialization的方法。

 

package com.jp.tic.framework.flex.converter;

import java.util.HashSet;

import java.util.Set;

import org.springframework.flex.core.io.AbstractAmfConversionServiceConfigProcessor;

public class CustomAmfConversionServiceConfigProcessor extends AbstractAmfConversionServiceConfigProcessor {

    private static Set<Class<?>> classes = new HashSet<Class<?>>();

    @Override

    protected Set<Class<?>> findTypesToRegister() {

        return classes;

    }

}

如果你还需要添加更多自己的转化服务，那么你需要给CustomAmfConversionServiceConfigProcessor 注入conversionService对象。

<!-- 添加配置类型转换器、转换服务 -->

    <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">

         <property name="converters">

            <list>

                <bean class="com.jp.tic.framework.mvc.convert.StringToTimestampConverter"/>

                <bean class="com.jp.tic.framework.mvc.convert.DateToTimestampConverter"/>

            </list>

        </property>

        <property name="formatters">

            <list>

                <bean class="com.jp.tic.framework.mvc.formatter.SimpleDateTimeFormatAnnotationFormatterFactory"/>

                <bean class="com.jp.tic.framework.mvc.formatter.TimestampFormatterFactory"/>

            </list>

        </property>

    </bean>

 

 

<bean id="customConfigProcessor" class="com.jp.tic.framework.flex.converter.CustomAmfConversionServiceConfigProcessor">

    <property name="conversionService" ref="conversionService"/>

</bean>
